ProQuest Dialog Updates

Peek at early published biomedical literature

These “ahead of print records,” intended to provide very early access to the published literature, may lack volume, issue, and page information. However, when the NLM updates these records with full publication information, they are overwritten with a new document and changed publication status. Figure 1 illustrates the document status flow.

• Publisher — These records are, per the NLM, “citations electronically submitted for articles that appear on the Web in advance of the journal issue's release; i.e., ahead of print citations.” Following publication of the completed issue, the item is queued for issue level review and released in “In-Data-Review status.”
• In-Data-Review — First step in quality control. Records will typically either be reissued as In-process status records or go to PubMed-not-MEDLINE final record status.
• In-Process — Bibliographic data is checked, but no MeSH^® terms added yet.
• MEDLINE — Rigorous QA, MeSH headings and other indexing added.
• PubMed not MEDLINE — Records have undergone quality review but are not assigned MeSH headings because the item is not in scope for MEDLINE either by topic or by date of publication

Finding the records
ProQuest gathers these Publisher records, which are not provided with the regular feed from the NLM, and loads them onto ProQuest Dialog™ with the other MEDLINE data daily.  Here’s how to find and identify these records.

In the advanced search form, limit MEDLINE searches to a specific document status.

In command line, limit MEDLINE searches to a specific document status using the DSTAT field code.

Document status is displayed in the indexing details under “MEDLINE document status.”  Take a look below at the “PubMed not MEDLINE” record on ProQuest Dialog.

See Publisher records and other citation statuses in MEDLINE for more information.

 

It’s easy on ProQuest Dialog

Link Field Codes to understand a database, and use it for all it’s worth!

Have you ever started a search and wished you had printed out the ProSheet or made note of certain field codes for a particular database?  Now you can link to field code lists for the most commonly used databases in ProQuest Dialog. This search concerns a research project using Advanced Search to find articles in MEDLINE^® about Alzheimer’s Disease written by authors affiliated with the University of Pennsylvania.

Start with the field codes drop-list. For example, make the thesaurus term Alzheimer Disease a major MeSH^® descriptor with MJMESH. Sometimes, however, you want to see and understand the whole database’s structure. Click Field codes above the drop-list.

The help screen opens in a separate window showing the active database’s field codes. The full list of field codes is available for 10 files, including MEDLINE^®, Adis R&D Insight, Embase^®, BIOSIS Previews^®, Current Contents Search^®, Derwent Drug File, Inspec^® and more.

Browse and identify fields that will help you gain the highest precision. The help page gives the field names, the field codes, search examples and descriptions and notes about the fields.

Enter an author affiliation with the field code AF followed by the institution in quotation marks within parentheses.  Since ProQuest Dialog interprets spaces between words as AND, the quotation marks ensure the exact phrase and avoid false drops, such as University of Pittsburgh, Pennsylvania. 

Press Search.  Results return, and from here you can use Search Within and Narrow results by facets or browse and select records to view and work with.

Additional Publisher records on MEDLINE

Additional Publisher records have been added to MEDLINE^® on ProQuest Dialog from 2010, 2011 and early 2012, bringing our total number from approximately 80,000 to about 150,000. Sometimes known as “ahead of print” records, the NLM’s official name for them is Publisher records. See related article in ProQuest Updates.

• Publisher records dated 2012:  90,617
• Publisher records dated 2011:  56,935
• Publisher records dated 2010:    2,114

These Publisher records are now kept in the database instead of being deleted with each annual reload. For more on Publisher records and other citation statuses, see the NLM’s website.

 

Conference Abstracts in Embase

Since papers presented at conferences often significantly pre-date published research, sometimes by a year or more, conferences can represent the most current research in any given area. So, you’ll be glad to learn that Conference Abstract records are now available in Embase^® for the first time. Making this data available in Embase is a significant enhancement to the database and responds to your need to access the most current data.

More than 2,000 different conferences are covered from 2009, and the archive currently contains over 650,000 such abstracts of papers presented. Approximately 200,000 abstracts are expected to be added to Embase annually.

This data will be available on ProQuest Dialog during the week of May 14, 2012, and will be added to the Dialog file in the near future.

Identify Conference Abstracts in Embase
These records can be identified by a new entry in the Document Type box on the Advanced Search page. Select this to explicitly search just Conference Abstracts. Or, if using Command Line, search as DTYPE("CONFERENCE ABSTRACT").

Affect on Alerts
All of these records are new to the database. Even though they go back to 2009, if any match your Alert search strategy, they will be delivered. The broader your strategy, the greater your potential for retrieval

If this is the case with your Alerts, you can amend your Alert search strategies to affect retrieval:

• Add NOT DTYPE("CONFERENCE ABSTRACT") to your search; this will exclude any of these documents from Alerts retrieval.
• Include a date limiter in your search — e.g. AND PD(>20111231) — to ensure only data with a publication date after December 31st 2011 is considered.
• Amend the Alert profile to include 'Newly published documents only' (see below); this ensures anything with a publication date more than 90 days before the Alert is run is not delivered.

 

ICONDA updating resumed

ICONDA — International Construction Database (File 118) has resumed updating on Dialog and is no longer a closed file.  Monthly updates from October 2011 through March 2012 are now online, and all associated Alerts have been run.

They won’t know you’re watching

In addition to using Alerts in Derwent World Patents Index^® (DWPI℠) (File 351) to monitor competitor activity, why not also use Derwent Patents Citation Index^® (DPCI℠) (File 342) to alert you to known competitors citing your patents. Check out the following scenario to see what we mean.

You have a top five competitor list you currently watch. Derwent Patents Citation Index can be used to set up an additional watch that sends you a citation database record. This also shows you who else has cited your published patent, helping you identify new players in a specific area and potential new competitors.

Just follow these steps to search for a specific competitor citing your patents:

B 342	Begin 342
S CO=COMPETITOR/CG AND PA=MYCOMPANY	Enter the desired competitor name after CO=,  followed by the Citing Patent suffix /CG and your company name after PA=

Now you can review the results and set up an Alert to show when this competitor cites your patents. To follow additional competitors, simply repeat the steps.
